Project Progress Report

National Synchrotron Light Source II

August 2013 Activity

Another of many “firsts” at NSLS-II: About 100 participants from the 35th International Free-Electron Laser Conference, held in New York City and organized by BNL, came to tour the linac, booster, and storage ring on August 30, 2013. Can you spot the coach bus inside the ring? Part of the pre-tour arrangements included an exchange of drawings and photos with the bus company to establish the route to the inner courtyard and confirm the clearance in the vehicle tunnel, which was originally designed for a fire truck and easily accommodated the coach bus. report due date: September 20, 2013 Steve Dierker NSLS-II Project Director

OVERALL ASSESSMENT The National Synchrotron Light Source II Project continued to make satisfactory progress with the current-month schedule performance index (SPI) of 1.07, +$0.47M. The cumulative cost and schedule indices are 0.99 and 0.97. The project is 87% (90%) complete with 37% (48%) of contingency and management reserve for the remaining EAC (BAC) after the inclusion of the recently approved scope additions for future beamlines. The project has 45% (10 months) of schedule contingency for the remaining duration of 22 months before the projected completion date of June 2015 for CD4.

Accelerator Systems continued to make good progress on installation of the storage ring (SR) and integrated testing. The monthly SPI for Accelerator Systems in August was 1.65, +$0.88M, with a cumulative SPI of 0.95. Extended Integrated Testing of the entire injector complex, including transfer lines, continued in August. Installation of Accelerator Sys-tems is about 93% complete.

Experimental Facilities made good progress on delivery and installation of major beamline components, although delivery of some components was delayed into September, resulting in a monthly SPI of 0.89 (-$0.32M). Factory acceptance tests for a number of major components for various beamlines were successfully completed and integrated testing started for the HXN, CSX, and XPD beamlines.

Preparations for the September 16–20 Instrument Readiness Review (IRR) are well underway. The Injector IRR, and the resolution of findings resulting from it, will be part of the run-up to the Accelerator Readiness Review (ARR) planned for October that will enable commissioning of the booster.

Anticipating NSLS-II operations, a First-Experiments workshop was held on August 12–13. It had an excellent turnout, with 262 registered attendees—nearly 60% from outside of BNL. Several emerging science themes across the workshop included Complexity and Dynamics, Functional Materials, Biological and Environmental Systems, and Mesoscale Science. The workshop related to five of the six project beamlines: due to schedule overlap with an inter-national conference on inelastic x-ray scattering (IXS), a separate IXS workshop has been scheduled for October 1st.

The Project continues to strive to complete all necessary activities to enable project early finish by June 2014. However, schedule optimization has been implemented already and all built-in schedule floats are exhausted. Early finish of the project by June 2014 is still possible, but it will be very challenging to achieve.

The Upcoming Events calendar is on p. 7 this month.

ACCELERATOR SYSTEMS Magnet power supplies (PS). The two main dipole PS have been delivered and installed, and acceptance testing is completed. The power converters have been interfaced to the FPGA-based current regulator and PLC controls. Testing continues on the test load. First articles of the AC-powered amplifiers have been received and testing is underway. Fifty percent of the regulator chassis have been tested and installation will start in September.

Installation of Booster to Storage Ring Transport Line (BST) power supplies is almost complete. A small amount of work is being coordinated with the BST-II magnet and shielding installation groups. After a repair, the booster dipole power supply BD1 was successfully tested. Staff are working to get sufficient spares for the booster dipoles.

Electrical utilities connection work resumed in the Compressor building and the rest of the RF building. Electricians finished installing tunnel cable tray for the injection straight. We have finished the conduit work needed for the wireless network in the linac, booster, and storage ring tunnels. The installation of routers and antennas will begin in September. High current PS testing is complete in pentants 1–4. Low current PS testing is in process in P5. Smoke detector installation in the RF racks is finishing.

Magnets. Parts for 80 (of total 90) fast corrector magnets have been received; the magnets have been assembled, tested, and installed in the accelerator tunnel.

Supplemental shielding. The analysis of supplemental shielding in the storage ring has been completed. The shielding analysis was reviewed by the Radiation Safety Committee and accepted with a few small action items. The design for the shadow shielding for the G2 dipole girders has been completed and manufacturing is underway. The conceptual design for the movable heavy shielding in the injection region had to be revised. Final design is in progress. Materials for SR supplemental shielding are on order.

RF. The first unit of the superconducting cavity was successfully tested in the vertical test cryostat. The test was very successful and yielded a Q of greater than 109 up to accelerating gradients of 9MV/m (Fig. 1). Assembly of the cavity in its cryostat has begun.

The installation of the cryogenic plant was completed, which leaves only the piping connections into the tunnel to be installed before commissioning can start. The last sections of vacuum jacketed cryogenic piping for connection to the tunnel and to the block-house have been delivered.

Vacuum. One of two vacuum sections of BST-II was assembled, pumped down, and checked for leaks. After cable termination, a vacuum of low 10-8 Torr was achieved. The C23 straight section and cells C01 and C22 were assembled and successfully in-situ baked. The header drops of both synchrotron radiation absorbers and vacuum chambers for all five pentants are now completely installed and connected to the Cu and Al cooling water headers. Cell-to-cell PLC cables and some additional vacuum cables were pulled. Termination has started. The 1st article of the Beamline Front End vacuum PLC was received and successfully tested. Development of PLC logic has started.

Insertion devices (IDs). Four out of six damping wigglers (DWs) have been delivered to BNL. Unit 5 is in transit and is expected to arrive by mid-September at BNL. The Critical Lift Plan needed to transport the tested DW to the ring building has been written (using the template of the B832 Lift Plan) and submitted for review. The vacuum chamber stands and DW floor plates have been installed in cell 28 and are awaiting survey. The first DW will be delivered to the ring building in mid-September. Cable tray installation in the ring is complete for all straight sections which accommodate the first suite of IDs. Spare cables and connectors are received for both DWs and elliptically polarizaing undulators (EPUs).

The two EPU units safely arrived in the presence of the Contractor representatives. A Critical Lift plan has been worked out specifically for the CSX EPU. The devices have been moved on their air casters into the insertion device laboratory. The test program for the first unit has begun.

Timely delivery of the EPU Vacuum Chamber is a concern since the vendor is having difficulty with their NEG coating process. Solutions to the issues with NEG coating are being investigated. The ID and vacuum team is working closely with the manufacturer to resolve the issues. The IVMM has been installed for acceptance testing in the ID laboratory. Tuning of undulator IVU21 (for the SRX beamline) has been completed by the manufacturer. A draft piping diagram was created for connecting the BNL-supplied chiller to the device. The cell 5 straight section layout has been modified at the request of the Diagnostics group and has been accepted by all parties involved. The first article of the Short Straight Section Canting Magnets will arrive at BNL in the first week of September. Once the PDR is completed, the first set of three magnets can be delivered by mid-October. The first device of the undulator IVU20 production completed initial leak check and baking will start in September. The second device is in the process of final tuning. The TiN coated permanent magnets for undulator IVU-22 (for the IXS beamline) have been received by the manufacturer. The vacuum system design has been completed and RFPs for building the vacuum portion have been issued by the manufacturer. The March 2014 delivery schedule is unchanged. The FDR for the undulator IVU23 production (contribution of the NSLS-II

project to the NEXT beamlines) was held. Findings and action items are being discussed with the manufacturer.

Installation and integrated testing. The end date of installation without IDs is currently projected for Dec 2013. The end date of installation with IDs is currently May 2014. The critical path for accelerator installation runs through shielding installation, booster commissioning, flow meter capillary tubing, SR area monitors, injection straight, with the RF cavity near the critical path (<60 days).

Cable pulling is in process for beamline frontends in cells 3, 5, 23, and 28. Water- and air-line installation is in process in cells 23 and 28. The fast correctors are in the process of assembly and installation (70 of 90 installed). Profiling of the SR magnet/girders is continuing (15 of 30 complete). Other survey work included the LtB TL, the BtS TL, booster berm, injection septa, cell 30 diagnostics, beamline support, and preliminary survey of the Petra cavity.

Testing of the linac and booster PPS system is complete, and testing of the P1/P2 PPS system is underway; certification of the entire injector PPS will follow in early September. Search mirrors will be installed inside the SR tunnel at each ratchet wall.

Installation of horizontal and vertical scrapers in cells 1 and 30 are complete. Installation of the beam loss monitors is in process. Transverse feedback installation is in process in cell 16. Installation of the RF beam position monitor (BPM) pick-up cables will start in mid-September.

The following installation activities of Conventional Facilities have occurred in August. The experimental floor roof deck rework is complete. The mezzanine roof deck rework is complete and scaffolding disassembly is in process between columns 4 and 8 (cell 27), which is scheduled to be completed in early September. Scaffolding assembly is complete on the SR mezzanine (cell 30) to fireproof columns 13–15. Drywall work will start in early September. The P5 DI piping has been opened to the primary DI system, but the flow is lower than expected. The situation is being investigated to determine if the cause is air in the system or a damaged underground valve. The cause of air handler ground fault errors is still being investigated.

Electrical utilities. Installation of the ODH system in the RF building is in process. AC power work for the damping wiggler racks will continue in cell 27 after the roof deck scaffolding has been removed. Installation of the router conduit for the tunnel wireless network is in process. Installation of the injection straight cable tray is finishing. The cable tray in cell 22 for the vacuum cables is complete.

Mechanical utilities. The installation of the P5 aluminum DI drops is complete (Fig. 2). Acceptance testing of the SB-5 copper pump skid is complete. The heater on the BR-3 pump skid has been repaired. The SB-4 copper pump skid pump was inspected by the vendor and may have an issue in the gearbox. It will be watched closely over the next few weeks. The P1 and P4 PCHW heat exchangers have been repaired and are awaiting insulation delivery before being put back into service. These two pentants are currently being cooled by the adjacent pentants. The capillary tubing installation is in process (pulling through the offset conduits is ~75% complete

EXPERIMENTAL FACILITIES In August, Experimental Facilities continued to make good

progress and is holding at only 2 months delayed from the baseline schedule. Optics and beamline components are arriving and being installed at CSX, XPD, CHX, and HXN. The schedule performance of beamline component vendors has been carefully monitored and most components are scheduled for Factory Acceptance Tests (FATs) and delivery to BNL close to the contracted schedule. A few delays are anticipated, but none that will prevent beamline readiness at the NSLS-II early completion. Utility installation work is ongoing at HXN, CSX, XPD, and CHX. This work is now carefully coordinated with the schedule for delivery of beamline components so that the installation of utilities is completed prior to the installation of beamline optics and components. With beamline components now installed, the integrated testing phase is beginning for HXN, CSX, and XPD.

CHX. The NSLS-II First Experiments Workshop attracted large and enthusiastic participation from the user community. Many ideas for early science experiments at the CHX beamline were presented and discussed during the two-day workshop. The idea of measuring “mesoscale” dynamics in materials on time scales which are more than 100x faster than what was ever possible before triggers, for obvious reasons, much enthusiasm in the community.

Important progress was also made with procurements. The CHX diffractometer was successfully shipped to BNL and assembled into its final location by Norman Huber from Huber Diffraktionstechnik GmbH, assisted by the entire CHX team (Fig. 3).

The contract for the CHX SAXS table, the last major procurement included in the initial project baseline, was awarded (August 24) to GNB Corporation Inc., a small business located in Sacramento, CA; preliminary design work is now underway. The Transfocator project is progressing well. Details of the design were discussed in a meeting held mid-August at NSLS-II with two engineers from the contractor, JJ-Xray, Inc. The mechanical design for this important device is now close to final. The first major piece of equipment was installed in the CHX endstation.

CSX. The FATs for the monochromators for both branches were successfully completed at FMB-Berlin and the devices were delivered to BNL. Planning for the installation in September is well underway. Terminations of vacuum cables were undertaken for the coherence branch, and the vacuum sections were successfully powered and gauged to the equipment racks. The controls group started the task of remote programming all of the vacuum gauges and power supplies. Cable pulling has started for all the FOE and coherence branch motors and encoders. Machined parts for the differential pump support and the coherence branch gas cell were received from BNL Central Shops, along with parts for the monochromatic diagnostics. Assembly of these will begin in September.

Figure 4. Installation of CSX beamline components on the experimental floor. IXS. The FAT for the IXS KB Mirror System was success-

fully completed at Toyama Co. on Aug 7–9 (Fig. 5). The system is now in transit and is scheduled to arrive at BNL the week of Sept 30. Installation of the system on the beamline will follow. The production of the KB mirrors and benders is making excellent progress and is on schedule. The FAT for these items is scheduled for Oct 9–11 at WinlightX.

Figure 5. IXS KB Mirror System at Toyama during the FAT.

The RFP for the multilayer motion mechanism for the IXS spectrometer is in the final negotiation stage following the vendor selection process. The contract is expected to be placed in early September. The RFP for analyzer and multilayer mirror vacuum chambers was posted and vendor proposals are due on Sept 11. Finally, mechanical utilities installation on hutches B, C, and D was started and is progressing well.

HXN. After installation of the beamline components in the first optical enclosure, 3-ID-A (Fig. 6), 100% of the cables have been terminated and tested. A vacuum pressure of 3 x 10-8 has been reached for the horizontal focusing mirror before bake-out, which will take place in fall. Evaluation of the vendor proposals for the HXN microscope vacuum enclosure has been completed and the vendor has been selected. The contract is expected to be awarded in early September. Substantial progress for the HXN X-ray Microscope controls has been made. A closed-loop scan of nanopositioners with the interferometer has been implemented and achieved a tracking error of ±2 nm. The tracking error is largely attributed to the ambient temperature (in)stability. We are planning in-vacuum tests in next few months. The HXN beamline development is on track.

SRX. The supplier Bruker-ASC has made very good progress in fabricating the components for the SRX Optical package; a FAT for major components is scheduled for September. WinlightX is encountering delays in deliveries from subcontractors for mechanical and vacuum parts. A FAT is now scheduled for October. Both companies are making progress; no significant schedule risk is anticipated. The SRX team continues to closely monitor advancements in the work of both suppliers. Measurements of the performance of the sample stage for the high-flux setup are nearly finished; the results are influencing procurement details for the high-resolution stages. Complex sample environments have been developed further by scientists from several BNL-funded research projects, from the Beamline Advisory Team (BAT), and from other academic institutions. Early science experiments were discussed in depth during the Early Science Workshop, held at NSLS-II on August 12 and 13. A subsequent BAT meeting on August 14 focused as well on commissioning tasks and early science experiments.

XPD. Phase 1 of the XPD beamline components installation and survey is complete and includes: the Diamond Filter assembly and its support, the frame for the fixed aperture mask and bremsstrahlung collimator (Fig. 7), the shielded beam transport pipe in A through C (Fig. 8), and the end optical bench and the high resolution monochromator in end station C (Fig. 9). Phase 2 installation is due to start Sept 5 and will include the filter array, white beam slits and filter assembly, white beam stop, bremsstrahlung stop, monochromatic beam slits, fluorescent screen, and beam position monitor assembly. Some additional items will still be in the factory in Oxford in September, as FMB-O are experiencing some difficulties with completion of these items. The current plan is to organize a Phase 3, with delivery of the remaining items on Nov 4 and installation in the first two weeks of November.

Figure 7. Frame for the fixed aperture mask and the bremsstrahlung collimator is in place. The assembly, comprising the pair of diamond windows/filters, has been installed and verified by BNL Survey

Figure 9. High Resolution Monochromator and the End Optical bench are installed and their alignment has been verified by BNL Survey.

Laue-Laue monochromator (DLM) Part 1 Revision: A full report on the mechanical tests and FEA was submitted by FMB-O and reviewed on 8/9. It is agreed that the J-shape is the best solution for the foil arrangement, which will be implemented. Part 2 Manufacturing: the delivery of material to FMB-O for Part 2 continues to be an issue; holiday shut-downs by various vendors introduced delays. Currently, only ~55% of material has been delivered to FMB-O. The start and finish dates for the work orders have had to be moved. The result is a further delay to the DLM project of about one week. Currently the FAT date is ~11/7, with delivery due in early December. There is some uncertainty regarding this delivery.

The vertical focusing mirror manufactured by Winlight-X was completed. Current vacuum is 4 x 10-9 torr, baking might not be needed. End item documentation is all delivered.

Diffractometer – RPI. The Heidenhain ring encoders were received Aug. 9. Assembly of the spindle (Fig. 10) began Aug. 12 and was completed on Aug. 28. A rotation test was carried out in the factory and failed on one detector circle due to corrosion of the bearing. The replacement bearing is due for delivery Sept. 5. The detector mounting plates are complete and will be delivered to RPI on Sept 9. The FAT is provisionally set for Oct 15–18, with delivery ~Nov 18–22.

For the x-ray pho-ton counting pixel area detector, a new batch of sensors was under test; the elec-tron counting mode and Schottky diode are the preferred con-figuration for the XPD CdTe chip.

Tests also revealed that the C10 detector requires regular reset and recalibration cy-cles to neutralize polarization effects. Delivery with a built-in depolarization cap-ability is scheduled for October 2013.

Goniometer. The goniometer (Fig. 11) features a large-diameter precision angular contact bearing and a substantial stainless steel support. It is driven by a sine arm arrangement actuated by an in-vacuum linear translation stage working through a wobblestick. The crystal cage takes a channel-cut crystal and is mounted on the end of the drive shaft of the goniometer. The crystal is a channel-cut Si(111) with 5 mm vertical gap which will accept a 30 mm H x 2.6 mm V beam over the whole energy range (30–70 keV).

Figure 11. Goniometer assembly.

Lead/steel enclosures 28-ID. Mechanical utilities in the D-hutch are complete except for the valves, which have not been delivered. Installation of electrical utilities in 28-ID-D is nearly completed. Completion of the inside of the hutch is pending the delivery of more cable trays. Cable terminations

to A-hutch racks are in progress. All other racks were lifted on top of hutches. PPS conduits in the 28-ID are installed and PPS boxes are starting to be fabricated now.

Multi-analyzer crystal x-ray detector. The SOW and Specification have been revised and submitted for final approval before the release of an RFQ. The current estimate of ARO-to-delivery time is 28 weeks.

Robotic sample manipulator. The kick-off meeting with Square One Systems Design, Inc. took place at BNL on Aug 20. The Preliminary Design Review is scheduled at BNL on Sept 19.

The X-ray flat panel detector I is completed. The detector is being mounted on a support and will soon be tested at X17A at the NSLS, prior to being used at XPD.

Early science preparation. At the NSLS-II First Experi-ments workshop (Aug 12–13), the XPD breakout session gathered a large audience (54 attendees in the room and ~14 on webcast). The videos of the talks can be seen at http://www.bnl.gov/ps/nsls2/beramlines/xpd-talks.php. Software develop-ment was said to be critical for all aspects of XPD, including rapid data acquisition, analysis, simulation, and visualization. Specialized expertise and infrastructure are needed in automated data analysis and visualization software, using modern modular programming paradigms that allow for rapid feature extensions driven by scientific need. Another take-away message of the workshop is that XPD will have immediate positive impact in a large number of critical areas. The workshop raised awareness that the time demand for the XPD beamline will be very high on day-1. It is anticipated that the experimental protocols and tools developed and the equipment being purchased at XPD will leverage the capacity of NSLS-II for a growing diffraction community.

COST/SCHEDULE BASELINE STATUS August’s current-period schedule variance (SV) for the overall project was $469K, with an associated schedule performance index of 1.07. The improved performance was due primarily to Accelerator Systems, $883.5K. The cumulative SV for the project had green status, with an SPI of 0.97 (-$23.3M).

The current-month cost performance index (CPI) for the NSLS-II project in August was 1.08 ($506.5K). The cumu-lative Project CV (cost variance) continued, with green status at 0.99 (-$9.4M).

For Experimental Facilities, WBS 1.4, schedule perfor-mance in August was negative for the month with an SPI of 0.89 (-$318K) due to delays in beamline installation. The cumulative SPI remained at 0.91 (-$5.5M).

For Conventional Facilities, WBS 1.5, schedule perfor-mance for August was negative with an SPI of 0.71 (-$143K), red status, which is minor relative to the total cost of the construction contracts. The cumulative SV is (-$788K), with an SPI of 1.00, green status. The cumulative CV is (-$450K) with a CPI of 1.00, green status.

Accelerator Systems, WBS 1.3, continued its excellent schedule performance in August with a monthly SPI of 1.65, +$883.5K and cumulative SPI of 0.95 (-$15.5M). The cumulative CPI remained at 0.95 (-$14.2M); the current-month CPI was 1.02, +$36.3K, green status.

Accelerator Pre-Ops, WBS 1.6, showed a slightly positive current-period SV of +$45.7K, SPI 1.03, and a negative current-period CV of (-$57.9K), CPI 0.96. Cumulative schedule variance continues to be negative with a SV of (-$1.5M), SPI 0.94, and a positive cumulative CV of +$8.1M, CPI 1.46. The CV is due primarily to underruns in Project Management PreOps.

The Project was approximately 90% complete as of August 31, with approximately 48.4% remaining contingency/ Management Reserve (MR) on BAC work remaining. The Project EAC was $897,731K, and MR/Contingency was approximately 36.66% of EAC work remaining. Project percent complete is 87.2%, based on EAC work remaining. At the end of August there was approximately $42.4M remaining of Contingency and MR for the Project.

The critical path was updated in August and now runs through the Booster Commissioning, Safety Assessment Document/Accelerator Safety Envelope (SAD/ASE) activities for SR Commissioning, IRR/ARR preparation activities for SR Commissioning, SR Commissioning, Insertion Device Installation, and Integrated Test activities. There are 9 months of float between the Project’s projected completion (Sept 2014 for all scope additions) and CD-4.

ENVIRONMENT, SAFETY, AND HEALTH There has been significant progress in addressing actions needed to commence injector commissioning. The Linac and Booster revised Accelerator Safety Envelopes (ASEs) have been approved by BHSO, along with associated Unreviewed Safety Issue (USI) documents that addressed the Extent of Condition Review for supplemental shielding. PS has developed and implemented an Instrument Readiness Plan to assure PS management that the project is ready for commissioning. The Plan will be followed by an Instrument Readiness Review in September. The IRR is being led by F. Kornegay, a former Spallation Neutron Source employee and a prominent figure in the DOE accelerator community. The remainder of the team consists of BNL staff from across the complex, including the accelerator and ESH directorates. The IRR Plan of Action is substantially complete. Planning is also underway for the Accelerator Readiness Review, with potential team candidates being identified. Actions identified in the Corrective Action Plan (CAP) for the Linac Event are essentially complete, with approval required for a few documents and approval of the Conduct of Operations Matrix by the BNL Conduct of Operations Board and DOE.

To focus staff on achieving the injector commissioning schedule, significant changes were made to the ESH organi-zation in August. These changes include realigning responsi-bilities for authorization basis document preparation, training, procedure development, accelerator readiness, and beamline readiness. The desired effect is to ensure all staff are working in an integrated fashion to address actions necessary for commissioning.

Construction of the Satellite End-Station Building-2 (SEB-2) was started in August, after a groundbreaking ceremony at the end of July. The facility will house the Soft Inelastic X-ray experimental facility. Operational Readiness Evaluations (OREs) have been completed for the seven remaining LOBs. These labs are being used to assemble and test beamline components. The ORE and BORE (Beneficial Occupancy Readiness Evaluation) processes ensure that life safety, code compliance, and work planning/controls are in place prior to commencing with laboratory work. Work to complete the ring building conventional construction activity punchlist items continues and is nearly complete. There has been significant progress in the build-out of several of the six project beamlines. To date, all 18 hutches have been completed, and utility installations are well underway. Experimental equipment is being installed at several hutches.

In late August a new USI condition was identified concerning the soil that shields the Linac and Booster. Survey measurements of the berm showed that the soil shielding cover depth was less than that specified in the Safety Assess-ment Document, in several areas. The issue has been reviewed and the insufficient shielding does not increase the hazard level of the facility nor expose the public, employees, or environment to unacceptable levels of radiation. A USI evaluation and SAD addendum are being prepared to address the finding.
